Hi Dave

Your spot on. If I open the e mail that has the file in and then open the file this opens up ok in excel with the correct file name.

However if after this i then close the e mail which contains the saved file whilst the file is still open in excel you get the normal reminder "A program still has the file attachemnt " ".xls opem. changes to this doc................."

If you then close the excel spreadsheet and then reopen outlook and try to reopen the file this is when it gets renamed, and as you say if you search on the file name it is in the C drive temp folder.

I assume this temp folder is cleared each time the pc is shut down, however any thoughts on how i could stop the file being stored in the temp folder after i shut down the e mail containing the file ?
